Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a cofferdam device for water conservancy construction. Background Technology

[0002] Cofferdams are temporary structures used in water conservancy projects for construction in water areas. They are mainly used to enclose water areas, drain water, and provide a suitable construction environment, ensuring construction safety and project quality. Cofferdams are particularly important in the construction of rivers, lakes, and canals.

[0003] Existing hydraulic construction cofferdam devices require installation in the construction water area to contain the water flow and facilitate subsequent construction. These cofferdams are typically constructed of reinforced steel or concrete, and their height is usually slightly above the water surface and cannot be adjusted. During rainfall, the water level rises, causing external water to intrude into the cofferdam, endangering the safety of construction workers. Therefore, this solution proposes a hydraulic construction cofferdam device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a cofferdam device for water conservancy construction to solve the problems mentioned in the background art.

[0028] refer to Figure 1-4 As shown:

[0029] Example 1: This utility model provides a cofferdam device for hydraulic construction, comprising:

[0030] Outer cofferdam 1;

[0031] The inner cofferdam 8 is fixedly installed inside the outer cofferdam 1. The top of the inner cofferdam 8 is provided with an extension groove, and the inner wall of the inner cofferdam 8 is provided with a moving groove.

[0032] Mounting bracket 5, multiple mounting brackets 5 are fixedly installed on the inner wall of the top of the inner cofferdam 8;

[0033] A support frame 6 is inserted and connected to the end of the mounting frame 5 away from the inner cofferdam 8. A bolt 7 is inserted and connected to the end of the mounting frame 5 away from the support frame 6. The threaded end of the bolt 7 is threaded and connected to the end of the support frame 6 near the mounting frame 5.

[0034] It should be noted that the inner cofferdam 8 is fixedly installed inside the outer cofferdam 1. The outer cofferdam 1 protects the inner cofferdam 8, preventing water flow from directly impacting it. At the same time, the outer cofferdam 1 provides initial obstruction of the water flow, preventing it from intruding into the construction site. Multiple mounting brackets 5 are fixedly installed on the inner wall of the inner cofferdam 8. The ends of the mounting brackets 5 away from the inner cofferdam 8 are all interlocked with the support brackets 6. One end of the bolt 7 is interlocked with the end of the mounting bracket 5 away from the support bracket 6, and the other end of the bolt 7 is threadedly interlocked with the end of the support bracket 6 near the mounting bracket 5. The support bracket 6 and the mounting bracket 5 are fixed by the bolt 7, and the support bracket 6 provides support and reinforcement to the inner wall of the inner cofferdam 8.

[0035] Multiple reinforcing steel plates 2 are fixedly installed at one end of the outer cofferdam 1 near the inner cofferdam 8. The ends of the multiple reinforcing steel plates 2 away from the outer cofferdam 1 are all fixedly connected to the ends of the inner cofferdam 8 near the outer cofferdam 1.

[0036] It should be noted that one end of the multiple reinforcing steel plates 2 is fixedly connected to the inner wall of the outer cofferdam 1, and the other end of the multiple processed steel plates is fixedly connected to the outer wall of the inner cofferdam 8. The inner cofferdam 8 and the outer cofferdam 1 are reinforced by the reinforcing steel plates 2 to prevent deformation of the inner cofferdam 8 and the outer cofferdam 1 due to water flow collision.

[0037] In Embodiment 2, this utility model provides an extension mechanism, which is applied to a water conservancy construction cofferdam device in Embodiment 1. The extension mechanism is set in an extension groove and includes an extension part and a moving part. The extension part is slidably inserted into the extension groove, and the moving part is fixedly connected to the end of the extension part away from the outer cofferdam 1. The moving part is used to drive the extension part to move.

[0038] Specifically, the extension section includes an extension cofferdam 9, one end of which is slidably inserted into the extension groove, and the end of the extension cofferdam 9 away from the outer cofferdam 1 is fixedly connected to the movable section.

[0039] Specifically, the mobile division includes:

[0040] The movable plate 12 has one end inserted into the movable groove and fixedly connected to the end of the extended cofferdam 9 away from the outer cofferdam 1.

[0041] The driving component is located inside the inner cofferdam 8, and the driving component is threadedly connected to the end of the moving plate 12 away from the extended cofferdam 9.

[0042] It should be noted that one end of the extended cofferdam 9 is slidably inserted into the extended groove, and one end of the movable plate 12 is inserted into the movable groove and fixedly connected to the end of the extended cofferdam away from the outer cofferdam 1. When the water level rises, the driving component is activated, which drives the movable plate 12 to move. The movement of the movable plate 12 drives the extended cofferdam 9 to move, causing the extended cofferdam 9 to slide up and down in the extended groove. This causes one end of the extended cofferdam 9 to move out of the extended groove and be higher than the top of the inner cofferdam 8. The extended cofferdam 9 is used to contain the external water flow, preventing the external water flow from intruding into the inner cofferdam due to the rise in water level, thus improving construction safety.

[0043] Specifically, the driving components include:

[0044] Threaded rod 11, one end of which is rotatably inserted into the bottom of the inner cofferdam 8, and the outer wall of threaded rod 11 is threadedly connected to the end of movable plate 12 away from the extended cofferdam 9.

[0045] The drive motor 10 is fixedly installed on the top of the support frame 6, and the output end of the drive motor 10 is fixedly connected to the end of the threaded rod 11 away from the moving plate 12.

[0046] It should be noted that one end of the threaded rod 11 is rotatably connected to the bottom of the inner cofferdam 8, and the other end of the threaded rod 11 is fixedly connected to the output end of the drive motor 10. The drive motor 10 is fixedly installed on the top of the support frame 6. When the water level rises, multiple drive motors 10 are started simultaneously. The output ends of multiple drive motors 10 drive multiple threaded rods 11 to rotate, so that multiple threaded rods 11 rotate synchronously. The rotation of the threaded rods 11 drives the moving plate 12 to move, and the movement of the moving plate 12 drives the extension cofferdam 9 to move, so that the extension cofferdam 9 slides up and down in the extension groove, so that one end of the extension cofferdam 9 moves out of the extension groove and is higher than the top of the inner cofferdam 8. The extension cofferdam 9 blocks the external water flow, preventing the external water flow from intruding into the inner cofferdam due to the rise in water level, thus improving construction safety.

[0047] A diversion plate 3 is fixedly installed at one end of the outer cofferdam 1. A support plate 4 is fixedly installed on the inner wall of the end of the diversion plate 3 away from the outer cofferdam 1. The end of the support plate 4 away from the diversion plate 3 is fixedly connected to the end of the outer cofferdam 1 close to the diversion plate 3.

[0048] It should be noted that the diversion plate 3 is fixedly installed at one end of the outer cofferdam 1, and the support plate 4 is set between the diversion plate 3 and the outer cofferdam 1. One end of the support plate 4 is fixedly connected to the end of the diversion plate 3 near the outer cofferdam 1, and the end of the support plate 4 away from the diversion plate 3 is fixedly connected to the end of the outer cofferdam 1 near the diversion plate 3. The diversion plate 3 is set at the upstream end of the outer cofferdam 1. The water flow is diverted by the diversion plate 3 to prevent the upstream water flow from directly impacting the outer cofferdam 1 and to improve the stability of the outer cofferdam 1.
